SYNOPSIS

#include <sys/types.h>
#include <crypto/rijndael.h>
int
rijndael_makeKey(keyInstance *key, u_int8_t  direction,  int
keyLen,
        char *keyMaterial);
int
rijndael_cipherInit(cipherInstance  *cipher,  u_int8_t mode,
char *IV);
int
rijndael_blockEncrypt(cipherInstance  *cipher,   keyInstance
*key,
        u_int8_t *input, int inputLen, u_int8_t *outBuffer);
int
rijndael_padEncrypt(cipherInstance   *cipher,    keyInstance
*key,
        u_int8_t    *input,    int   inputOctets,   u_int8_t
*outBuffer);
int
rijndael_blockDecrypt(cipherInstance  *cipher,   keyInstance
*key,
        u_int8_t *input, int inputLen, u_int8_t *outBuffer);
int
rijndael_padDecrypt(cipherInstance   *cipher,    keyInstance
*key,
        u_int8_t    *input,    int   inputOctets,   u_int8_t
*outBuffer);

DESCRIPTION

The rijndael_makeKey() function is used to set up the key

schedule in
key. The direction (which may be DIR_ENCRYPT or DIR_DE

CRYPT) specifies
the intended use of the key. The length of the key (in

bits) is given in
keyLen, and must be 128, 192 or 256. The actual key is sup

plied in the
buffer pointed to by keyMaterial. This material may be raw

binary data,
or an ASCII string containing a hexadecimal rendition of the

raw binary
data, dependent on a compile-time option in the

rijndael_makeKey sources,
BINARY_KEY_MATERIAL.

RETURN VALUES

The rijndael_makeKey() function will return BAD_KEY_INSTANCE

if a NULL
key is passed, BAD_KEY_DIR if direction is not DIR_ENCRYPT

or
DIR_DECRYPT, BAD_KEY_MAT if the key materials are not a hex

adecimal
string (and binary keys are not set), and TRUE otherwise.
